Draw a stacked area plot.
Parameters
----------
x : (N,) array-like
y : (M, N) array-like
The data is assumed to be unstacked. Each of the following
calls is legal::
stackplot(x, y) # where y has shape (M, N)
stackplot(x, y1, y2, y3) # where y1, y2, y3, y4 have length N
baseline : {'zero', 'sym', 'wiggle', 'weighted_wiggle'}
Method used to calculate the baseline:
- ``'zero'``: Constant zero baseline, i.e. a simple stacked plot.
- ``'sym'``: Symmetric around zero and is sometimes called
'ThemeRiver'.
- ``'wiggle'``: Minimizes the sum of the squared slopes.
- ``'weighted_wiggle'``: Does the same but weights to account for
size of each layer. It is also called 'Streamgraph'-layout. More
details can be found at http://leebyron.com/streamgraph/.
labels : list of str, optional
A sequence of labels to assign to each data series. If unspecified,
then no labels will be applied to artists.
colors : list of color, optional
A sequence of colors to be cycled through and used to color the stacked
areas. The sequence need not be exactly the same length as the number
of provided *y*, in which case the colors will repeat from the
beginning.
If not specified, the colors from the Axes property cycle will be used.
data : indexable object, optional
DATA_PARAMETER_PLACEHOLDER
**kwargs
All other keyword arguments are passed to `.Axes.fill_between`.
Returns
-------
list of `.PolyCollection`
A list of `.PolyCollection` instances, one for each element in the
stacked area plot.
